Legal trust I'm arranging for gold and silver expert? (12)

I believe the answer is:

metallurgist

I'm a little stuck... Click here to teach me more about this clue!

'gold and silver expert?' is the definition.
I can't judge whether this defines the answer.

'legal trust i'm arranging' is the wordplay.
'arranging' is an anagram indicator.
'legal'+'trust'+'im'='legaltrustim'
'legaltrustim' is an anagram of 'METALLURGIST'.

'for' is the link.

Can you help me to learn more?

(Other definitions for metallurgist that I've seen before include "Studier of certain elements or alloys" , "Scientist" .)

I've seen this clue in The Irish Times.
